This plugin can be a little tricky to understand. Try it before purchasing and be sure you read the documentation sections under each option. At some point, the demo page and contents within this plugin will be updated to make it simpler to use. Essentially, it will iterate through a list of items and allow to find and replace text within each item in the list. It runs client side and can be a brilliant tool in creating dynamic content very quickly. It works well though and I'm here for support if needed.
It allows you to iterate through a list of things and use the data to create dynamic content. For example, if you had 1000 users in your database and wanted to send them all the same message but change certain things like the name, email, phone number etc then you can do that by inserting tags within the initial content. Each tag is read and replaced with each row of data until you end up with a generated list of 1000 raw text messages all with individual content included.

If any of your fields contains another list of things, then you can specify the field for the secondary list and it will retrieve the data for each item there also.

Dynamic content can be written in either plain text or HTML.

It works in the same way as mail merges do but has been designed to run against lists in Bubble.

The plugin doesn't send an email, it only generates the content.
